Abstract
In this study, sawdust (SD) has used as a short natural fiber to reinforce acrylonitrile butadiene rubber / recycled natural latex glove (NBR/NRL-G) compound. Sawdust fiber (SD) has been grinded and screened to form (300μm-700μm) size. Different loading of (SD) (5,10,15 and 20 phr) has been used and prepared by two-roll mill machine at room temperature. Several tests were used to study characteristics and properties of this compound. The testing such as cure characteristics, morphology, tensile and physical properties are determined. The scorch time (ts2), cure times (t90), minimum torque (ML) and the maximum torque (MH) of NBR/NRL-G/SD increased with increasing of the sawdust content in the compound. This was contributed to the increase the time for crosslinking initiation and increases the adhesion bonding between matrix and filler. The 5phr loading of (SD) which filled the NBR/NRL-G compound was the higher tensile properties than other (SD) loading.
